The DC 4-1 JDM header is by far the best bang for the buck. But the best will steal your wallet.

Hytech, by far is the best. But you will pay alot. I've seen and witness alot of headers in the past, both mild to wild B-series motors. But it all boils down to what the motor wants too.


But if your making 196hp, or in the upper 190s all motor on standard 81mm bore (or 81.25 oversized), those numbers are perfect.


Now ifs its a 85mm bore LS block, whoa...............then there's something not right there.
